To all whom it may concern.-

Be it known that I, CHARLES H. 00X, of Haverhill, county of Essex, Stateof Massachusetts, have invented an Improvement in Snow-Flows, of whichthe following description, in connection with the accompanying drawings,isaspecification, like letters on the drawings representing like parts.

This invention relates to a snow plow, one of the principal objects ofthis invention being to provide a plow adapted particularly for streetrailway work.

In accordance with myinvention, the plow is provided normally with acentral located nose, extended rearwardly from which are two wingsadapted to direct the snow equally to opposite sides of the track. Atleast one of these wings is so hinged as to enable it to be swung intosubstantial alignment with and to form a continuation of the other wingto thereby direct the snow entirely to one side of the track as isnecessary when operating the plow upon double track lines.

If desired, a false nose may be used when the plow is to throw the snowequally at opposite sides of the track, said nose being removed andturned into an inoperative position when one of the wings is to be swunginto alignment with the other for the purpose specified. When in theirnormal positions, that is, in position .to throw the snow to oppositesides of the track, the said wings are preferably adjustable by suitablemechanism whereby their angle of divergence or spread may be varied tothereby vary the path left by the plow.

In the preferred construction the plow irre ular dotted line w-x Fi 1.

ber a, said triangles being braced in suitable manncr .by the divergingand cross braces a and a and connected by the substantially verticalmembers a a the top and bottom triangles, at the nose of the plow, beingconnected by the nose-post a B, B, are the two wings, shown as andpreferably hinged together and to the nose-post a by suitable hinges b,I), see Fig. 2, whereby the said wings may be spread into any desiredangle to vary the path formed by the plow. f

B, B, are two extension wings shown as and preferably pivotedat b to theprincipal wings Band adapted, when in their full line position Fig.1, toform a prolongation of the other wing, but, which when desired, may beturned upon their pivots in the direction of arrow 5, Fig. 2, intoposition behind the.prin c'ipal wings thereby rendering them in eifectinoperative.

In the present embodiment of my invention, the main frame of the plow,comprising the two triangles referred to, is pivoted in suitable manneras at a to a support shown as a triangular frame 0, Odetachably'connected at c, c, to the car platform. Upon this supportingframe 0, O, I have shown erected a suitable support 0', in bearings 0 ofwhich and also upon the frame 0 proper, I have mounted the worm shaft 00 provided at its upper end, and in convenient position for operation bythe driver, with an operating wheel 0 and at or near its lower. endwitha worm 0 in mesh with a worm wheel 0 which latter is geared to apinion 0 fast on a pulley shaft 0 journaled in suitable bearings in thesupporting frame. This pulley shaft 0 is provided with a pulley 0 aboutwhich is passed a cable or a chain 0 connected at its opposite ends tothe wings B, B, of the plow.

Rotation of the operating wheel 0 in one or the other direction, actsthrough the pulley and cable 0 to turn the main plow frame upon itspivot a, to direct its nose in a more or less angular direction to theright or tothe leftas may be necessary to follow the line of the trackin curving, said worm and worm wheel in themselves constituting a lockto re tain the plow in desired angular position.

To spread the wings B, B, I have herein provided a centrally arrangedlongitudinal slide bar 19 provided with guide slots 19 through which arepassed suitable guide pins, one of which is shown in Fig. lat 12 indotted lines, and to this slide bar are jointed toggle links 6 see Fig.1, said links being also jointed to the wings. The slide bar 6 is movedlongitudinally by means of a pull rod b having its end fitted with ahandle 11 in convenient position for the operator. hen the slide rod andtoggle links b are moved into their dotted position Fig. 1, the wings B,B, will be moved into and held in their dotted position, as shown, thesaid links being preferably moved past their center line so that thepressure of the snow against the wings will not tend to close thelatter. WVhen the wings are in the position represented in full linesFig. 1, the snow will be directed equally to opposite sides of thetrack. I prefer to provide the nose of the plow with a removable nosepiece D, the same as herein shown, being hung upon a suitable pivot d,Figs. 1 and 2, and when in normal position, as shown in full lines,locked by means of a lock pin or a bolt cl passed through the nose posta WVhen it is desired to direct the snow entirely to one side of thetrack, as in double track work, the locking pin or bolt d is removed andthe nose piece D is swung about its pivot d intoits dotted position Fig.2, and one of the wings B turned upon its hinge 1) into the position,indicated in dotted lines Fig. l, the said wing then being insubstantial alignment with and forming a continuation of the other wingto direct the snow entirely to one side, the wing, when turned asdescribed, being held in its new position in suitable manner as by astrut, shown at b in dotted lines Fig. 1.

It is obvious that either wing may be turned as described to direct thesnow to either side of the track.

To raise the nose of the plow to enable the latter to more easily passfrogs and switches, I have herein provided a shoe 6, pivoted at e to thenose piece of the frame. This shoe may be thrown into its dottedposition Fig. 2, to raise the nose of the plow from the ground, bystraightening the toggle links 6 in suitable manner as by links 6 joinedto one end of the lever 6 pivoted at a and operated by a suitable rod eprovided with a handle e in convenient position for operation by thedriver.

F, F, are suitable scrapers adapted to scrape the track and provided, asshown, with teats, f, f, to clear the flange way, the said shoes, asshown, being carried by a suitable frame,

shown as consisting of the uprights f'f', adapted to slide, in suitablebearings f said uprights being connected by the crown piece f whichlatter may be raised or lowered by the toggle links f controlled by asuitable handlef which when turned into a vertical position, as shown inFigs. 1 and 4, raises the scrapers and when turned into a horizontalposition drops the said scrapers upon the rails.

In practice I prefer that the plow rest directly upon the snow, I havingherein shown, the lower frame triangle as provided with a cross bar I),see Fig. 2, the same being rounded at its under side to ride upon thesnow, although the said' plow may be otherwise mounted if desired.

My invention is not limited to the particular embodiment herein shownfor the same may be varied and still come within the spirit and scope ofmy invention as claimed.

Having described my invention, and without limiting myself as todetails, what I claim, and desire to secure by Letters Patent, is-- 1.In a snow plow, a combination with a frame of two wings secured thereto,one of said wings being hinged at its front end to enable it to beturned into substantial alignment with and to form a continuation of theother of the said wings, and a false nose piece arranged at the apex ofthe plow and hinged to enable it to be turned upward and backward whenthe two wings are turned one into alignment with the other,substantially as described.

2. In a snow plow the combination with a frame of two wings securedthereto, one of said wings being hinged at its front end whereby it maybe turned into substantial alignment wit-h and to form a continuation ofthe other of said wings, and a false nose and means to removably securethe same in operating position, substantially as described.

3. The herein described detachable plow, the same consisting of asupport and means to detachably connect it to a car body, a plow framepivotally connected to said support and provided with wings, and meanson and removable with the said support to turn the said plow frame onits pivot and with relation to said support, substantially as described.

4. In a snow plow, a supporting frame and means for detachably securingit to the car whereby said frame may be removed at will when the plow isnot needed, combined with a plow frame pivotally attached to the saidsupporting frame, and. means to vary the angular position of said plowframe, on andwith relation to said supporting frame, substantially asdescribed.

5. In a snow plow the combination with a car of a plow frame and alifting shoe located near the nose of the plow and means to raise theplow from and sustain its nose upon said shoe, substantially asdescribed.

6. The herein described snow plow, the same consisting of a support, andmeans to detachably connect it to a car body, a plow frame pivotallyconnected to and removable with the said support, and wings hinged to 5the said plow frame, and means on the said removable support to turn thesaid plow frame into one or another angular position with relation tosaid support, and means also mounted on the said support to spread the
